Headstock assembly is made of ball cup 10, ball head bushing 11, elastic rubber ring 12 and bushing pad 13；The ball cup 10 be by
The identical oblate cylindricality ball cup shell of upper and lower two structures is connected to each other composition, is provided at the center of ball cup 10 for control stick 3
The mounting hole passed through is equipped with the connection outer of annular, the top peace of the ball cup 10 in the middle part circumferencial direction of ball cup 10
In the ball cup installing port of mounting plate 1, the connection outer top surface of ball cup 10 is acted against on the bottom surface of mounting plate 1, described
The connection outer of ball cup 10 is bolted to connection on mounting plate 1；The bulb 9 is mounted on the center in ball cup 10
Position is separately installed with upper and lower two ball head bushings 11, the bulb lining between bulb 9 and upper and lower two ball cup shells
Using wear-resisting, coefficient of friction, small and durable non-aging oil-containing POM material is made set 11；Upper and lower two ball head bushings 11 will
Intermediate bulb 9 clamps, and is on the one hand fixed the rotation center of bulb 9, on the other hand forms spherical surface between bulb 9
Friction, so that control stick 3 is uniformly reliable along the turning moment of bulb 9, and effectively reduces vibration noise.The bushing pad 13 is pacified
Mounted in the bottom of the ball head bushing 11 of 10 lower inside of ball cup, it is supported with the ball head bushing 11 to lower section；The elasticity
In the top annular groove for the ball head bushing 11 that the installation of rubber ring 12 is pressed on 10 inner upper of ball cup；Elastic rubber ring 12,
Two ball head bushings 11 and bushing pad 13, which are mounted on together in ball cup 10, forms bulb seat assembly；The elastic rubber ring 12
After being compacted deformation, generated elastic force effectively eliminates the gap between bulb 9 and two 11 mating surfaces of ball head bushing, passes through
This simple structure compensates automatically after playing the role of abrasion.
As shown in figure 3, the connection arm assembly 8 is made of a connection cantilever crane and two spacer pins 14；Wherein, described
It connects cantilever crane to be welded to form by a splice sleeve of upper middle position with the monosymmetric bracket in lower part, the coupling sleeve pipe sleeve
It fills and riveting is fixed on the lower end of control stick 3, the pedestal upper end horizontal parallel and be symmetrically provided with two groups of mounting holes, two limits
Position 14 horizontal parallel of pin setting, and the equal riveting in both ends is connected in two groups of mounting holes of bracket and realizes fixation；In the pedestal lower end
Between be provided with hinge hole, which is transferred to telescopic rod for shifting movement for installing flexible joint element for bar 16, to realize.?
In vehicle travel process, along the hinged axially bored line below connection cantilever crane position occurs for the joint element for bar 16 that stretches due to Vehicular vibration
Limit distance is overcome between limited block at the top of rotation offset, the spacer pin 14 and flexible joint element for bar 16 and is interfered,
To limit the vibration offset of flexible joint element for bar 16, in addition, in order to reduce because of impact caused by interference, in institute
The external peripheral surface for stating spacer pin 14 is additionally provided with cushion blocking 15.In stationary vehicle, the outermost circumference table of the spacer pin 14
The distance between limited block side at 16 top of flexible joint element for bar of face and corresponding side is limit distance L, as shown in figure 4,
During being that flexible joint element for bar 16 is used cooperatively, due to the presence of lowermost limit distance L, so that the high vibration the case where
Under, the case where speed changer of flexible 16 other end of joint element for bar connection avoids the occurrence of off-gear, improve the operation of variable-speed manipulator
Reliability；Also just because of the presence of lowermost limit distance L, so that generating handle idle stroke S at the handle 4 on top, pass through tune
Whole limit distance L realizes that handle idle stroke S changes between 30mm-50mm.
Variable-speed manipulator assembly described in the utility model efficiently solves the sealing of full-float cab, vibration in summary
And the problems such as noise, while there is high reliablity, production cost is low and easy for installation.
